I have a static library compiled with Visual Studio and I want to link to it from MinGW.

I tried changing the suffix but I get a bunch of warnings like: Warning: .drectve /DEFAULTLIB:"uuid.lib" /DEFAULTLIB:"uuid.lib" /DEFAULTLIB:"MSVCRT" /DEFAULTLIB:"OLDNAMES" ' unrecognized.

Also a few errors including: ./libetpan.a(Release_ssl/mailimap.obj):(.text[_mailimap_noop]+0x7): undefined reference to___security_cookie'`.

Any help is greatly appreciated.

You can try to convert the .lib to .a with

.lib and .a are not the same format. Changing the file extension is lying to the linker, which is why it isn't working.

If it is a 32-bit library you are trying to link, it should "just work." MinGW supports 32-bit .lib files. If it doesn't, file a bug report.

If it is a 64-bit library, and you are using MinGW-w64 or something based on it (like the TDM-GCC 64-bit version) see the MinGW-w64 FAQ entry:

gendef mylib.dll
dlltool --as-flags=--64 -m i386:x86-64 -k --output-lib libmylib.a --input-def mylib.def
